Listen to web browsers

Now, we want to see how the Restlet framework can listen to client
requests and reply to them. We will use the internal Restlet HTTP server
connector (even though it is possible to switch to others such as the
one based on Mortbay's Jetty) and return a simple string representation
"hello, world" as plain text. Note that the Part03 class extends the
base ServerResource class provided by Restlet:

If you run this code and launch your server, you can open a Web browser
and hit the http://localhost:8182. Actually, any URI will work, try
also http://localhost:8182/test/tutorial. Note that if you test your
server from a different machine, you need to replace "localhost" by
either the IP address of your server or its domain name if it has one
defined.

So far, we have mostly showed you the highest level of abstraction in
the Restlet API, with the ClientResource and ServerResource classes. But
as we move forward, you will discover that those two classes are
supported by a rich API, letting you manipulate all the REST artifacts.
